This inve 'tion relates to line spacing de'-' vices for typewritingmachines.

The ob ect of the invention is to furnish a simple, easily operated and effective device by means of which the'platenmay be rotated to the. required extent to space the lines of t ewritten matter. J

- ith this endin view the invention consistsin the novel features of construction and combinations of 'parts to be hereinafterdescribed and finallyfipointed out in the claims.

In the accompanying drawings, in which the same reference characters denote corresponding parts throughouhFigure 1 is a side elevation of a line spacmg device constructed in accordance with the invention.

Figs. 4'and 5 show in 7 side elevation further modifications of the de- Fig. 6 is a rear elevation, partly in vice. section, of Fig. 5. Fig. 7 is a side elevation of another form of the device, certain parts being. indicated in dotted lines. .Fig. 8 is a top plan view of the device shown in Fig. 7,

all the parts being shown in fulllines. Figs. 9 to 13 are side elevations of other forms of line spacing devices constructed in accordance with the invention. .Fig. 14 is a rear elevation, partly in section, of the device shown in Fig. 13.

In the drawings 1 indicates the platen which is of the usual form, 2 the platen-shaft, and 3 the supporting frame having upright end-portions in which the shaft 2 is journaled. I The platen carries at one end, preferably the right handend as it is mounted in the machine, a ratchet 4. Saidratchet is spaced laterally from the upright end-portion of the frame 3, as shown, and it is within this space that several of the operative parts of the spacing device are located. I

In all the formsof the device shown in the drawings the operation of the spacing mechanism is effected through the manipulation of an actuating rod 5 which extends for- Specification of Letters Patent.

'wardly from the supporting frame, at one end of the latter, toward the operator. Said rod is located in. a plane parallelto that in which the ratchet 4 is located and is disposed horizontally, having at its outer end a depending handle-portion 6. The rod 5 is journaled at its intermediate portion in a sleeve-shaped bearing 7 which is preferably formed integral with one of the'upright .end portions of the supporting frame and extends transversely of saidportion'at' its outer. face. By means of the handle-portion '6, the actu ating rod 5 is turned in said bearing, and the movement is transmitted to the ratchet 4 and to the platen by a pawl-carrying arm mounted on the platen shaft adjacent said ratchet and'by various transmitting devices,

as will'nowbede'scribed.

Referring particularly to Figs. .1 and 2,

8 denotes an arm plvotedloosely nearone,

said pawl-carrying arm by means of-"a in ll)" passingtransversely through said .re and provided at one end with a hook 11. Said pin operates in a rectangular opening 12 in the end of the supporting frame and. is con-"- nected with a hook 13 carried by the arm 8 beyond its as shown. Therotation of the platen is effected by the turning of the actuating rod in its bearing, whereby the shorter end of the pawl-carrying arm is pulled downthrough the connection described, and the upper end raised in order to push forward the ratchet by means of the pawl 9. Said awl carryin arm is normally in. substanti.' ly horizonta position and after the actuation of the platen and the release of the actuating rod, pulls back by gravity into this position. The actuating rod is likewise returned to its initial position by the weight of its handle-portion 6 which is turned upwardly in order is advance the platen, and b'y'its connection with the wgravity returned pawl-carrying arm.

14 denotes a check-pawl of any appr ved construction, which acts on the rate let teeth and insures the sto plpa'ge of the platen in the proper position. we extent to which the platen is rotated is governed by the with a transverse slot 151. A pin 152 car amplitude of the movement of the actuating rod, and this is limited, in order to effect the desired spacing, by a suitable stop device.

In Figs. 1 and .2 I have shown a preferred ,form-of sto device. The sleeve bearing 7 has rotatab e thereon a collar 150 provided ried by-the actuating rod passes through a transverse slot 153 in the bearing 7. and into I the slot 151 of the collar" 50. Said collar is provided at its rear edge with a series ofsmall indentations'orrecesses 154 adapted to engage a pin 155 on the sleeve bearing 7.

r A helical spring 156 is interposed between a pin 15? atithe' forward edgeof said bearing anda milledflange' 158 on the collar 150, and normally forces said collar into engagement with. the pin- 155 so that said pin fits within -'one of the'recesses 154. l The collar 150 may be set angularly on the'hearing 7 by pulling the former against the action of the spring 156, the milled flange 158 being gras ed for this Jurpose, and then turning the col ar un-' til t e proper recess 154 is opposite the pin .spectively may be'brou ht more or less into register and consequent ly the actuating rod 1.52 will be permitted to transverse the entirelength of thesleeve bearing slot 153 when the actuating rod is turned, or only a predetermined part of the length of said slot.

Consequently. the amplitude of movement of the pin 152 and actuating rod is controlled, so thatgsaid ro'd will be turned to space one,

two or more times, as desired.

In. the formsho'wnin Figs. 3 and -3 the actuating rod is provided atits inner end with a beveled pinion 16 operating in an opening 17 in the end of the'supporting frame. A cam 18 having an inclined edge is journaled in an arm 20 of said :frame which extends upwardly from the lower edge of the axis by means ofa beveled pinion 21 carried thereby and meshing with-the pinion 16 on the rod. The pawlcarrying arm 8 is pro:

vided near its'pivot with a cam-portion 22 having an inclinededge abutting against. the inclined edge of the cam 18. The rotation of the cam 18 'by means of the actuating rod and thepushing 11 Ward. of the arm 8 by the cooperation of sai cam with the cam-portion 22, effect the rotation of the platen, as will be understood. 1

. F1 whic In the form shown in Fig.4 'the pawl-carrying arm 8 carries at its pivot a beveled pinion 24 which meshes with a similar pinion 25 carried by the actuating rod at its inner end.- vThe operation of this form of the de vice will be very readily-understood.-

gs. 5 and 6 illustrate a construction in aperture in the frame.

the pawl-carrying arm 8 is bent latorally at its pivoted end, the lateral portion being provided with an inclined edge 26 to cooperate with a cam 27 mounted on the inner end of the actuating rod 5. The turn ing of said rod to the right causes the cam 27 to depress the lateral inclined portion of the pawl-carrying arm and to raise the pawl, The parts are returned to their initial position of gravity, as in the forms hereinbefore described.

The pawl-carrying arm may have a hookshaped end; 28 extending lieyond the pivot,

as shown in Figs.-- 7 and 8, this end receivm a smaller roller 29 extending laterally from t 1e actuating rod at the inner end of the latter. In said figures, 30 denotes the pawl-carrying arm. The roller 29.0perates in a suitablev It is evident that the turning of the actuating rod toward the right will turn the roller 29 in downward direction andthis in turn will depress the shorter end of the arm 30 whereby the pawl9 at the other end of said arm moves forwardly and advances the ratchet and platen.

Fig. 9 illustrates a construction in which the su porting frame is'provided with a rectangul r. opening 31 and, extending upwardly from the lower edge of this opening is an arm 32 in which a unate or crescent shaped cam 33 is 'ournaled. Said cam carries a beveled pinion 34 which meshes with a similar pinion 35 carried by the actuating rod 5. :The pawl-carrying arm 36 is pro-- vided near. its ivot with an enlargement 36; and exten ing laterally from this onlargement and into engagement with the up per concave ed e of the lunate cam is a small antifriction ro ler 37. Said roller is located close to the pivot of the pawl-carrying arm, and when said arm is in its normal position, shown in Fig. 9, is midway ofthe length of the concave edge of the cam. It is ap arent that the rocking of the actuating r0 in its bearing causes the cam to move the shape of the cam, thereby oausmgthe advance of the pawl and of the platen.

A flexib e wire or similar device 40 is attached at one end to the upper edge of the pawl-carrying arm 41 between thepawl and the ivot, and at the other end to said ulley. he turning of the actuating rod will carrying arm to be pulled upwardly an give a platen-advancing movement. The parts are returned to their mitlal or normal position by gravity, as heretofore. j 1

Instead of being positive, the connection between the actuating rod'and the pawl-carrylng rod may be frictional, as illustrated in Fig. ll. In said figure, 42denotes a small friction-Wheel mounted on the actuating rod evidently cause the and-- and provided with a beve'led circumference.- Said wheel is; rotatable in an opening 43 in the supportingframe and frictionally contacts-with a similar frictioniwheel 44 mountedon the awl-carrying arm 8 'at the pivot thereof.

The operation of this form of the device will be manifest. In the construction shown in'F1g.- 12, the
